The helper Html.Beginform that marks the beginning of a form does not contemplate its fields.

Analyzing your code is as if in your form there was only one button:

<div class="form-group">
        @using (Html.BeginForm("Adicionar", "Usuario", FormMethod.Get))
        {
            <button type="submit" value="Create" class="btn btn-success">Cadastrar</button>
        }
        <button type="button" class="btn btn-success" id="btn-login">Login</button>
</div>

Adjust your code by including in the form (within the helper Html.Beginform) all fields and how in your controller you define [HttpPost] in the Add action, also change the Formmethod.Get parameter to FormMethod.Post:

...
<div class="form-group">
        @using (Html.BeginForm("Adicionar", "Usuario", FormMethod.Post))
        {

        <!-- INSIRA O CÓDIGO DO FORMULÁRIO AQUI -->

            <button type="submit" value="Create" class="btn btn-success">Cadastrar</button>
        }
        <button type="button" class="btn btn-success" id="btn-login">Login</button>
</div>
...

Example:

Model:

public class Usuario
{
    public String Nome { get; set; }

    public String Email { get; set; }

    public String Senha { get; set; }
}

View:

@model WebApplicationMVC.Models.Usuario

@{
    ViewBag.Title = "Adicionar";
}

<h2>Adicionar</h2>

@*A linha de baixo ou @using (Html.BeginForm("Adicionar", "Usuario", FormMethod.Post))*@
@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>Usuario</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.Nome, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Nome, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Nome, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Email, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Email, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Email, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Senha, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Senha, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Senha, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}

Controller:

    [HttpGet]
    public ActionResult Adicionar()
    {            
        return View();
    }

    [HttpPost]
    public ActionResult Adicionar(Usuario user)
    {
        Repo.Adicionar(user);
        return View("Index");
    }
